Do Cooking Classes for Nutrition Students Improve Their Eating Competence and Cooking Skills? A 1-Year Follow-Up in a Sample of Brazilian Public University Students

<b>Background:</b> The decline in traditional cooking practices and the increased consumption of ready-to-eat meals have raised concerns about dietary quality and health, especially among university students. Nutrition students, despite their academic training, often struggle to translate theoretical knowledge into healthy eating practices. Culinary classes in academic settings have emerged as promising strategies to enhance both cooking skills (CS) and eating competence (EC). <b>Objectives:</b> This study aimed to evaluate the impact of a 12-month cooking class program on the development of culinary skills and eating competence among nutrition students at a public university in Brazil. <b>Methods:</b> A longitudinal study was conducted with 42 nutrition students who completed a structured questionnaire at three time points: baseline, after 6 months, and after 1 year of participation in sequential cooking-related subjects. Data were collected using the Brazilian Cooking Skills and Healthy Eating Questionnaire (QBHC) and the Brazilian version of the Satter Eating Competence Inventory (ecSI2.0™BR). Statistical analyses included a repeated-measures ANOVA and a Pearson correlation. Bonferroni post hoc comparisons were conducted following the repeated-measures ANOVA to identify the time points at which significant differences occurred. <b>Results:</b> Participants, predominantly young females (78.6%, mean age 21.07 ± 2.71 years), demonstrated high CS at baseline and showed significant improvements over time (<i>p</i> < 0.05). At baseline, 59.5% of participants (<i>n</i> = 25) were considered competent eaters (EC ≥ 32). Knowledge in cooking terms and techniques increased after one year (<i>p</i> = 0.023). EC mean scores classified participants as competent eaters at the beginning and after one year, with an increase in the internal regulation domain. Improvements in technical culinary knowledge were associated with gains in contextual skills. <b>Conclusions:</b> Participation in structured cooking classes positively influenced the development of CS and EC internal regulation among nutrition students.
